ALOYSIUS WANEY, OF ST. LOUIS, MISSOURI, ASSIGNOR OF TWO-FIFTHS TO ROBERTBASILE, OF ST. LOUIS, MISSOURI.

LADDER SHOE.

Application filed September 11, 1920. Serial No. 409,578.

To all whom it may concern:

Be it known that I, ALOYSIUS WANEY, a citizen of the United States,residing in the city of St. Louis and State of Missouri, have inventedcertain new and useful Improvements in Ladder Shoes, of which thefollowing is a specification.

My invention relates to a ladder shoe, or antislipping device and, hasfor its object to provide a device which can be quickly attached to thelower end of one of the side rails of a ladder to permit the ladder tostand in an equalized position on a sloping roof, or other surface,without slipping or standing in a slanting position to one side.

A further object of the invention is to provide a shoe provided withspring members to frictionally hold the shoe to one of the rails'of theladder when applied thereto.

A further object of the invention is to provide an extension leg havinga bifurcated, or yoked lower end, one of the arms of said end beingprovided with a swivel foot provided with a rubber, or equivalentcontact surface for use when standing on a slate, or tin roof, and, theother arm being provided with a pointed end for use when the ladder isstanding on a sloping wooden surface, or its equivalent.

A further object of the invention is to provide novel means for holdingthe extension leg at any desired elevation, or adjusted position withrelation to the shoe.

With the above and other objects in view, the invention consists in thenovel features of construction, arrangement and combination of partshereinafter fully described and finally pointed out in the claim heretoappended.

Referring to the accompanying drawings forming a part of thisspecification wherein like characters of reference denote similar partsthroughout the several views:

Fig. 1, is a front elevation of a ladder equipped with a ladder shoeconstructed in accordance with my invention, the same being shown asstanding on a slanting slate, tin or equivalent roofing surface.

F ig. 2, is a view similar to Fig. 1, showing the ladder standing on asloping surface such as wood, or its equivalent.

3, is a view of the device, partly in vertical sectional and partlyinside eleva- Fig. 4, is a sectional View taken on line 4- 1 ofFig. 3. 1In carrying out the aim of my present invention, I employ a ladder shoe1 having an open top and a closed bottom 2 to prov de a ladder railreceiving socket 3. The front and rear walls 4 and 5 of the socketmember are each provided with a leaf spring member 6 which springs aresuitably fixed at their upper ends to the walls 4 and 5, as illustrated,their lower ends being free to y eld as the lower end of a ladder rail Ais inserted into the socket 3. These spring members 6 yieldingly bearagainst opposite faces of the ladder rail A to hold the ladder shoe fromslipping off of the rail A after the rail A has beeninserted into thesocket 3, as is manifest.

The side wall 7 of the shoe is provided with a boss 8 which is providedwith a longitudinal opening 9 to receive supporting leg 10. Thesupporting leg 10 is adjustable vertically within the opening 9 and isheld in any desired position with relation to the shoe 1 by means of aneye-bolt 11 which is provided with a winged-nut 12. The eyebolt 11 isreceivable in a transverse opening 13 in the side wall 7 of the shoe 1and the supporting leg 10 passes through the opening of the eye-bolt.The eye-bolt engages one of the grooves 14 of the supporting leg andwhen the nut 12 is drawn down, the eye-bolt holds the leg 10 fromslipping, as is manifest.

The lower end of the supporting leg 10 is provided with a forked endcomprising two diverging arms 15 and 16. Arm 15 is provided at its lowerend with a swiveling foot 17 which is provided with a rubber, orequivalent face 18 to prevent slipping thereof on a sloping slate, tile,or tin roof. The other arm 16 has its lower end tapered, or pointed, asat 19, to prevent slipping thereof on a sloping wooden, or equivalentroof, or similar surface. Both the foot 17 and pointed end 19 of thearms 15 and 16, respectively, are moved to a position in longitudinalalignment with the ladder rail A, when in service, as clearly shown inFigures 1 and 2, so that the end of the adjustable supporting leg 10which engages the roof, or other surface upon which the ladder isstanding, will come in alignment with the ladder rail A being supported,as is manifest.

It is evident, from the foregoing description, that my improvedanti-slipping ladder shoe may be quickly applied to the side rail of aladder and that it can be also quickly removed. It will be furtherobserved that when the shoe has been applied to the rail and the ladderraised to its desired position, that the supporting leg 10 can bequickly adjusted to hold the ladder in a straight and level positionwithout danger of tipping or moving side-ways, as it would were the shoeand extension leg not employed.

The many advantages of the herein de-- scribed ladder shoe will readilysuggest themselves to those skilled in the art to whichit appertains,such as fire departments, garpenters, painters, tuckpointers, and the.ike.

I do not desire to be understood asv limiting myself to the exactdetails of construction and arrangement as herein described andillustrated, as it is manifest that variations and modifications may bemade without departing from the spirit and scope of my invention and theterms of the following claim, hence I wish it to be understood that Ireserve the right to make any such changes, or modifications as mayfairly fall within the scope of the appended claim when fairlyconstrued.

WVhat I claim is:

The combination with a side rail of a ladder; of a ladder shoecomprising a socket member having a transverse slotted opening in one ofits side walls, a leaf spring fixed at its upperend'to the front andrear walls of the socket member and directed downwardly and inwardlywithin the socket member for frictionally engaging the front and rearfaces of a ladder rail for normally holding the shoe upon the ladderrail, a boss formed on the side wall of the socket member having alongitudinal opening, an extension rod having spaced circumferentialgrooves receivable within the opening of said bossv and telescopingtherewith, a screw threaded eye-bolt receivable in the transverseslotted opening of the side wall of the socket member, a nut for saidscrew-threaded eye-bolt for drawing the eye-bolt into engagement withsaid extension rod in one groove thereoffor holding the extension rod inits vertically adjusted position and the lower end of said extension rodbeing forked to provide two diverging legs, one of whichis provided atits free end with a swivel foot and the other being pointed at its freeend.

In testimony whereof, I have hereunto signed my name to thespecification.

ALOYSIUS WANEY.
